Description
Technical field
the utility model relates to the hydrophobic field of high-pressure heater, is specifically related to high-pressure heater drainage control system.
Background technology
The hydrophobic water lev el control of high-pressure heater substantially adopted float-ball type, electrodynamic type and pneumatic type before nineteen ninety, and these three kinds of traditional products can not meet need of production far away because of various drawback.After nineteen ninety, adopt " vehicle repair major Flow Technique " controlling water level, achieve breakthrough achievement.But the steam trap of traditional form use in all exist service life short and work insecure problem, long-term a large amount of steam water interface erosion spool, water lev el control extremely unstable, measures steam water interface simultaneously and enters air or hydrophobic pond, cause a large amount of heat-energy losses, cause very large resource waste.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high-pressure heater drainage control system, nothing is revealed, security performance is good, liquid level self-adjusting ability is strong, and can adapt to water-level fluctuation requirement when unit load 30%-100% changes, under nominal situation, water level maintains ± 50mm.
The utility model is achieved through the following technical solutions:
High-pressure heater drainage control system, comprise high-pressure heater, regulator plate valve, steam-water two-phase flow drainer and isolating valve, after bottom described high-pressure heater, drain water piping connects regulator plate valve, steam-water two-phase flow drainer, isolating valve successively, be communicated with the hydrophobic oxygen-eliminating device that goes, described high-pressure heater sidewall is provided with water-level gauge, high-pressure heater perisporium in water-level gauge height 1/3 ~ 1/2 scope is provided with a gas phase hole, gas phase hole is connected with the vapour signal port of steam-water two-phase flow drainer by phase transition tube, and phase transition tube is provided with steam gate valve.
The further improvement project of the utility model is, described gas phase hole site is arranged installs side near steam-water two-phase flow drainer.
The utility model further improvement project is, the pipeline of described regulator plate valve front end and isolating valve rear end separately connects bypass line, and bypass duct is provided with bypass valve.
The utility model further improvement project is, described drain water piping, bypass duct are DN65mm, and phase transition tube is DN25mm.
The utility model compared with prior art, has following obvious advantage:
The utility model steam trap vapour signal port is directly connected with controlled container by phase transition tube, the sampling of liquid level automatic regulating system signal directly gathers in controlled container, signals collecting is more accurate, control sensitivity higher, reduce and regulate vapour amount, reduce cavitation and the vibration of rear portion pipeline, especially 300MW, 600MW and above unit effect more remarkable.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Detailed description of the invention
As shown in Figure 1, the utility model comprises high-pressure heater 1, regulator plate valve 2, steam-water two-phase flow drainer 3 and isolating valve 4, bottom described high-pressure heater 1, drain water piping connects regulator plate valve 2 successively, steam-water two-phase flow drainer 3, after isolating valve 4, be communicated with the hydrophobic oxygen-eliminating device 8 that goes, described high-pressure heater 1 sidewall is provided with water-level gauge 5, high-pressure heater perisporium in water-level gauge height 1/3 ~ 1/2 scope is provided with a gas phase hole 11, position, described gas phase hole 11 is arranged at installs side near steam-water two-phase flow drainer as far as possible, and distance is more short better, gas phase hole 11 is connected with the vapour signal port of steam-water two-phase flow drainer 3 by phase transition tube, phase transition tube is provided with steam gate valve 6.The pipeline of described regulator plate valve 2 front end and isolating valve 4 rear end separately connects bypass line, and bypass duct is provided with bypass valve 7.
The course of work: when the water level in high-pressure heater rises, vapour amount signal reduces, and passes to steam-water two-phase flow drainer by gas phase pipe, and in steam-water two-phase flow drainer, liquid level rises, and hydrophobic displacement increases, and finally makes the water level decreasing in high-pressure heater; Otherwise when water level decreasing in high-pressure heater, vapour amount signal increases, pass to steam-water two-phase flow drainer by gas phase pipe, the liquid level in steam-water two-phase flow drainer reduces, and hydrophobic discharge rate reduces, finally make the water level in high-pressure heater increase, thus reach controlling water level object.
